To `all whom t may concern:

` Be it known that I, HERMAN Go'rrnsMAN, a citizen of Austria, residin at New York city, county and State of ew York, have inventedcertain new and useful Improvements in Lock-Operated Circuit-Glosers, of which the following is a full, clear, and exact description.

Th's invention relates to improvements in locks for doors or other closures, `one of the objects of my invention being to Provide an alarm system for locks that w-illindicate or soundv an alarm Vwhenever anyone tampers' with the lock in an attempt to open the door" or closure equipped with myv improved lock.

Inthe present embodiment of my invention, -I employ an electric alarm system, the circuit of which includes certain elements of- 22 the lock, said elements beingv arranged to:

close the circuitshouldI anyone'attempt to` set the combination and turn the knob which volperates the tongue or bolt-for the door or c osure.` v ,l

I will now proceedpto describe m tion in detail, referencey being vha invento the accompanying drawing, forming part hereof, whereinr- Flgure 1 is a plan v1ew of an embodiment of my mvention, the cover being removed;

Fig. 2 is a longitudinal sectional view of thel greater part of the lock, the sectionbeing taken on a line 2-2 in Fig. 1

Fig. 3 is anenlarged diagrammatic plan view of a portion of the lock;

F'g. L 1s an enlarged fragmentary plan combination; and

Fig. 5 is a diagrammatic face view illustrating a dooror closure.

As herein arranged, my improved lock consists of a casing 6 having at oneY end a slidably mounted tongue or bolt 7 to engage the hasp in 'a door frame 0r the like, saidv hasp and door-frame omitted. The tongue or bolt 7 isoperated by means of a bar 6a which in turn is operated by aI cam 7 carried by a shaftv 8 operablev by means of a .knob l9, the knob being located exteriorly of the door or closure, as indicated in Fig. 5.

l Within the casing 6, I place a train of inter-meshing gearslO, 11, 12, vl-and 14. The gear 11 is mounted on a tubulanshaft 15 within which ashaft 16 is located-carrying gear 12. The tubular shaft 15 also carries an hour-hand 17 and theI shaft 16 a -minutehand- 18.

As herein arranged, the mechanism is set so that the bolt or tonguev 7 can be moved out certain time. While I have indicated a dial 19 having time indications, letters or numerals could be used. When the hands 17 and 18 are moved, by rotating shaft 16 by means of the knob .20 to open the door or closure, a certain element ofY the lock is ,placed lin condition to permit of` the operation of the bar 6n to move the tongueor bolt ,7. To operate bar 6, I provide lthe cam 7 which is operable inthel direction of the arrow 21 b means of shaft 8 and knob 9.

To control t e movement of bar 6'L to open position, I provide a disk or-rotatable stop having serrations 23 (see Fig. 3), and a slot`24 (a gear may serve for this purpose), arranged'toreceive a tongue 25 carried by vbar 6*` when saidslot `is brought into alinement with the tongue 25. The disk 22 will be secured to gear 14 `and rotate with it.

-The proportion of the gearing will be prefer- (in this instance), the slot 24 in disk 22 will select the aline with the tongue 25. At such a time the bar 6* can be moved to move tongue 7 to open the door or closure. To change the combination, the hand ,18 will be removed from the squared end 26 of shaft 16' and replaced in a dierent position on the shaft. In this instance, the shaft 16 is arranged for four different combinations. V'Should the end of shaft 16 be hexagonal, six combinations would be provided for. The four combinations herein referred to, could be five-thirty, six thirty, seventhirty or eight -thirty. These combinations are merely illustrative.

At any time,other than when slot Maud tongue 25 are caused to aline, the tongue 25 would strike the disk 22 and engage one of the'serrations 23. The engagement of the serrations,-by said tongue, would prevent the operation of thehands 17 and 18 because the train of gears would be locked. Furthermore, when tongue 25 contacts with disk 22, a circuit for a bell 26 (in this linstance), would be completed and said bell would ring.` Y, l

To form 'a `circuit including bar. 6*- and disk 22, I mount said disk upon a conductor 2T connected -by a wire 28 to one4 side of a in disk 22 a battery 29. The op site side of the battery is connected by a Wire 30 to bell 26, the bell 26 being connected to a contact 32,- in the casing 6, by a Wire 31. The contact '32 bears ,against the bar 6a. It will be apparent that the bell will ring Whenever bar 6a is moved to the right, in Fig. 1, unless v the proper combinationA is set, because tongue 6? will strike the disk 22, and complete the circuit.

yShould the bar 6a be moved, by manipulat' ing knob 9, the bell would ring, giving notice that the lock Was being tampered with, but the door could not be opened, as such move- 7 to clear its keeper.-

- When ton ue 25 is moved into the slot 24 ter lthe proper combination has been set, the bell will not ringbecause tongue 25 will not touch the disk 22 as the slot 24 will be large enough 'to `receive the tongue Without said tongue touching same; hence the alarm circuit will not close.

-Having now described my invention, What I claim is 1. In a lock operatedcircuit-closer, a locking tongue or bolt, a bar to operate same, means tofoperate said bar, a rotary stopI adjacent t-he bar having a slot therein, a tongue carried by the -bar to enter said slot when ment would not be suiiicient to move'tongue the rotary stop is rotated to cause' the slot and tongue on saidbar to aline, means to rotate said sto and means carried by the .y

stop to coact with the tongue on the tongueoperating bar to prevent rotation of the ystop when the tongue on the bar and slot in the.

rotary stop are out of alinement. j.

2. In a lock operated circuit-c1oser, a train determined position and to contact with said i disk to complete the circuit should the bar be' moved at a time when the slot in said vdisk is out of alinement with ythe projection 'p on said bar, and'means to prevent the rotation of the disk When the projection` on the tongue-operating 'bar contacts with said disk. i

3. The combination of elements recited in claim 9, with the additional feature of serrations .carried by the disk to engage the projection on the tongue-operating-bar .when y the projection is moved'to contact with said disk.
